How long does it take for IOS7 to install?

My Iphone is asking me to install it but will it take long for it to install, because I need to use the phone, i have 43 mbps internet at home which i use as wireless on the phone, and i have Iphone 4s

Within 15 min
mine was about 5 min.

Took me 30 m

Everyone I know that has an iPhone/iPod said it took atleast 2 hours. Guess its different for some people

It really depends. Sometimes it may take 10 minutes or it might take an hour. But there's no really specific answer. It varies in time, mine took around 30-45 minutes.

It depends on the traffic from apples servers. Say 2 million people upgrade at one time. It will take longer because its having to push it. Pushing takes time. However this morning it could take 30 mins ( best I have heard all week.)

It varies depending on phone, Wi-Fi signal strength, Wi-Fi speed, how many people are on that network, how many devices are using that network, and the amount of traffic the servers have at Apple at the time.

Install it at home. My install in Ipad mini was about 15min which includes a full restart. Smooth pain free experience

  • Will all my files be erased when I install the official iOS7? As y'all know, the official event is being held right now where the iPhone 5S, 5C and iOS7 are officially going to be released. However, I was wondering if all my apps and files will be deleted and act like a fresh OS once I install it.
  • How long does it take an iPhone to recharge after it had been dead a long time? My cousin just gave me her old iPhone 5. It's in good condition but it's been sitting in her drawer for months. I don't know how many months but a pretty long while. Anyways, i out it on the charger and it hasn't moved from the red. It's been on maybe… At least a half hour. Is it okay? I don't know anything about these machines lol.
